Strange issues after screen replacement - ZenFone 2 Android Development

Last week I shattered the screen on my phone. I ordered a new screen and after some tinkering around everything worked fine so I thought. I have three issues that I can't explain. First now it says charging slowly whenever I try to charge it regardless of the charger. It takes about 8 hours to charge even with my fast charger. Next whenever I make a call the screen goes blank and it's almost impossible to wake it up, meaning if I need to use the keypad I can't. And third for some reason I have lost root, which is odd because I have a custom rom. Has anyone ever experienced any of these things or have an idea how to fix it?

are you on stock or cm 13 rom ?
about fast charging : i guess now you have a dead battery bro ...but before judging that ..try another (good) charger .if it wont get any better just try to charge it while it is turned off.
there is a quite possible that your board is effected too after the replacement .

Wrong place to put this Montenell

I'm on a cm rom. I've used several chargers all with the same result

Was the screen assembled properly?
My guess would be that the screen (digitizer) is partially covering the proximity sensor. This could happen if the screen isn't aligned properly or if it isn't glued properly and you have a gap between the glass and the proximity sensor.
About the slow charge..
when the damage to the screen ocurred it's possible, that the battery or the motherboard got damaged as well (seen this before).
I would try to remove the motherboard and reinstall it, doublechecking every connector while reconnecting everything.

[Q] charged,empty,charged, at nausem: can't run on battery anymore

My GT-N7000 yesterday developed this issue:
When I boot it (no USB cable to power it), the battery shows empty (grep battery icon, with a charging circle).
A second or so later, it switches to show a half-full battery, with charging dots below. and it vibrates for about a second.
Again, another second ro so later it goes back to showing an empty battery and the cycle continues.
If I attach a UCB charging cable, it boots fine, shows the battery as 100%
If I remove the charging cable, it loses power. When switched on again, this all starts over.
I saw this on ICS (4.0.4, stock, German) and there i also had the battery icon in normal more switching between
charging and blinking to not charging. I found a recommendation that upgrading might help, so I
did apply the JB update I had downloaded a few days ago, but this does happen
under JB too (OTA German 4.0.4, then flashed with Phil's-stock plus cwn6)
Is there anything can can be done? Is this a hardware issue or something that some form of total reset might cure?
As it is, I cannot use the phone w/o having it externally powered through my powerbank or car charger.
This happens with two batteries, so it's not the battery that is broken
I really think this one is battery problem as I have experienced the same thing..
are the batteries you tested New?
just my 2 cents.

No, I've had both a fow a while.
I may buy a third just to test but I fear I may have to get a replacement phone soon , sniff
Though I would suggest that you get a new set of batteries...they solved the problem for me.
While you are at it, please search the forum for another solution that worked for me- "cleaning the micro-usb slot"...its an easy process but needs to be done a little carefully.
either of the two would definitely work for you...speaking from experience!

Bro..i had the same problem..this morning,when the phone showed 100% in charged mode..as soon as i unplugged the charger..the charging %age goes down to 15% immedietly.. i went and bought a new charging port(only that usb charging port = very small),removed the old usb port and soldered the new usb port to the note..This works like charm..but this probably void the warranty ..so,if u want..its upto u..i wont recommend it but it works like charm for me

Display issue with samsung note n7000

My issue is with samsung note n7000. When battery inserted, screen is constantly on with strange horizontal lining. Also happens when display is dimmed. I took the phone apart and cleaned it with alcohol, that did the trick for about 20 hours. This morning started to do the same. Also, there's no warranty left. Posted a picture to show what the screen looks like when battery inserted.
I guess your battery is old..its time to change battery..I had faced same problem before now its allright with new battery...
I am noob.BUT.I am learning
tried with 3 different batteries... don't think it's battery related issue

Could be GPU overheating.
Could be screen overheating.
You could try underclocking the device to 800MHz, it will be dog slow, but should indicate if it is heat related.
Bottom line though, you probably need a new screen.
Search XDA/Google for how to fit a new screen.
Quite often those that have fitted a new screen will expalin why they did so.
If their symptoms are similar to yours then you need a new screen.
You could always give Samsung a bell (that's a phone call in case you're not UK).
Could be resolved

I think, this has happened due to overheating or overcharging. One of the connection point has become loose or soldering has melted. Get this phone to a service station to get this fixed. I dun think u need a new screen.
If you want to try for screen replacement, here's the youtube link:

You're probably bang on there.
It does sound like loose connections on reflection.

I have an extra n7000 as sparepart phone, which has working screen, did the same thing with another screen. Only when i changed the Charging Connector unit from the other phone, the screen went black, but didn't turn on. Could the charger unit cause all this?

I honestly don't know.
I don't know enough about the electronics in the device.
If you can find a service manual for the N7000 this might help.

Charging loop overnight? Screen may be damaged.

Hi everyone, yesterday I used NeMa's battery calibration to reset the batterystats on my Xperia Z3 Compact running the latest Cyanogenmod. I had done it when the phone was charged at 100% and noticed that the battery instantly dipped to 99% afterwards. I took note but I wasn't worried at the time. Last night I left the phone on its charging dock and slept for about 5 hours and 30 minutes. When I woke up I picked up the phone and noticed it was hot. The screen was fine at the time so I checked the battery percentage, saying it was stuck at 99% which leaves me to believe that the battery was stuck in a charging loop from a bad calibration. I texted someone and also noticed that the Swype keyboard was laggy and unresponsive, but with my lock password, etc. it seemed to be fine.
I powered the phone down and slowly tried to dissipate heat with warm water and later colder water. When I tried to power the phone on, it had shown normal booting until the end when the screen gave out. Currently, it will show normal LED lights up top and calls will still register, but the screen is dark and doesn't seem to have promising digitizer input because I can't answer the call even though I know where to touch the screen to answer it.
Has this happened to anyone? This is my first encounter dealing with this. Any fixes (screen response or proper calibration), or would I just have to get it repaired?
Hello, check this things out
only 2 ways to find out if the screen is working or not working at all
a) a very dark place... start the phone.. maybe the screen is not iluminted proprey ! and maybe the screen is visible ...but very limited.
b) buy a mhl to hdmi cable.. to connect from phone to a smartv.
And see if the touch respons.. if yes the only the screen i out.. if not the screen +touch is out ( dead)
Yeah the screen and digitizer are fried. I'm going to try and return it to the seller stating a defective battery. Has this happened to anyone else? I just need to know if there are any fixes to this if I were to get the same phone.

Poor seller, you blew up your phone with bad software and water and you want someone else to pay for it.

OnePlus 3T stuck on 50% battery

Hi
I have a OnePlus 3T stuck on 50% battery it doesn't go up or down, I tried letting the battery drain and then restarting, but it still displays 50% even after factory reset.
Is this a problem that can be resolved? I am not sure what else to try, I tried battery re-calibration apps and charging the phone a few times etc. but it did not work.
Hope you can help.
Thanks
Infinite Battery life? COOL!
Or did you mean the Indicator is stuck on 50% even when the Battery itself runs out and dies? If that, i can see it being an issue. We should start with the basics. What ROM? Bootloader state? Recovery? Kernel? Firmware? Mods? Length of time since last clean install. etc.
A Factory Reset seems like a good first step for now.
Haha, yes the indicator is stuck on 50%.
If I let it run out then recharge fully as they say to do to recalibrate, then even doing this overnight, it is still (apparently) charging in the morning - so I turn it on and it is still the same thing stuck on 50% and not recalibrated (if calibration is indeed the problem).
I moved to Lineage OS 15.1 (OFFICIAL) using latest TWRP recovery. Bootloader is unlocked.
It is now back on stock (latest build downloaded from oneplus) after full wipe of data/cache/dalvik, with stock recovery (bootloader still unlocked). The problem remains.
So as you can see a factory reset did not work I am afraid.

When it's been on charge long enough that it should have fully charged, it's still showing 50%, right? If you use it long enough to discharge completely, are you getting half the Battery life? (This is the difference between the indicator being faulty and the Battery being faulty).
If the indicator is correct and the Battery is refusing to charge beyond 50%, that's your Battery about to die. Send it to Oneplus for a replacement.
Thanks, yes if I leave it on overnight or otherwise more than enough for a full charge, it shows 50%. It is difficult for me to say if it lasts a full charge as I only just purchased the phone, so I have nothing to compare to.
However, the indicator does not slowly increase to 50%. I can fully discharge the phone until it turns off, and whilst doing so the indicator stays at 50%. I then go to charge the phone whilst turned off, and it doesn't matter how long I charge it for, almost always I turn it on and it is stuck at 50% (very rarely it looks like it's working, it starts lower and the level even seems to increase a few percentage points, going to say 15%, then it stops and I wait a while until it is clear it is not going to change, and eventually restart the phone, turn it back on and it's the same old deal, stuck at 50% no matter what).
I am not sure if this is very helpful, it's difficult to describe, I guess the bottom line is, no matter how long or little I charge it, almost always I turn it on and it is stuck at 50%, which made me think it was some sort of indicator problem, but I am not sure. I guess I should try and send it back as there's clearly a problem and I have tried reasonable steps to resolve.
Probably battery is fried
Damn, that's a shame, if that's the case I guess I should send it back then (although I can see the seller disputing it, I've barely used the device and it doesn't seem to be resolvable so I don't have a choice really).
I suppose I will rebuy OnePlus 3T unless there is an alternative, wasn't happy with recording quality which is a shame as I like to record guitar/singing, but everything else seemed great - I guess a new Xiaomi is another option as no trouble with battery, but I hear recording quality not so good.

I'm sure the seller was perfectly aware of this defect when they sold it. If the phone is in good condition otherwise, and if you got a good deal on it, you might consider getting Oneplus to service it. It's a gamble but it's still a great phone and a new Battery would give you at least two more good years with it. I'm sure we'll still be getting custom ROM support that long too.
Any other 3T you buy used now could face a similar issue any time soon and then you'd be in the same boat.
If it still has a warranty, then it's easily solved through official service.
If not, then if u bought it from a private seller, than good luck with convincing him about the problem

You need to have it serviced. I had that issue shortly after I purchased my 3T. I had tried all sorts of apps to see if it was charging and they all said it was, just not dash charging. Everything showed 50%, every app, any ROM, recovery, everything. Also, if I remember right, the battery wasn't exactly charging while plugged up, it just wasn't drawing juice from the battery. I know they replaced the motherboard but I can't tell you how much that would cost as it was under warranty.
if you are on OOS try *#808* check battery charging .if you get -40C its a problem with the motherboard

I had this issue just recently. See if the message "battery temperature is too low" appears when you try to charge when the phone is off. If yes you either have a broke battery or motherboard.
I had to get a replacement motherboard and battery to get my issue fixed.

For oxy? On custom roms used holy kernel
There are 3 possible solutions for this issue.
1: replace battery.
2: change the ROM for one that changes the Kernel for a version without this temperature protection.
3: fix or replace the main board.
To fix the main board you need to check 2 things on it.
On the left side of the battery connector (under a double sided glue tape foam), there are some SMD. The lowest two are related with this problem. I fix my board resoldering the one on the right (nearest to the connector). Be aware that the SMD is small and when are desoldered, it gets sticked on the double sided glue tape foam. I took a picture of it, but i don't know how to insert here.
If someone is reading this thread today and wants to know the solution,
This problem occurs when battery wire is connected loosely to motherboard or that connector has gone bad.
It has nothing to do with ROMs, kernel etc non-sense.
It's true, had the same problem after switching the battery of my OnePlus3T.
After reopening the device and reattaching the cable by CAREFULLY using more pressure and using a bit duct tape to fixate everything, it worked just fine.
Charging now works as it's supposed to and I'm again able to see the actual charge level.
Thanks lockhrt999!

Not charging

I got this phone 2 months ago brand new from ebay.
It had mostly working fine until today.
Battery was around 25%, so I plugged it in for charging. The charging connection kept disconnecting and reconnecting every second. I thought it could be a loose cable, but I checked everything. Eventually it connected, but the phone wasn't charging. I opened the settings and checked under battery, it said something like "connected, but not charging". I tried changing the charger, used 2 different charges but same result.
At this point it was clear the phone wasn't charging no matter what. I checked the USB port for dust, etc and also reset the phone. I also noticed the phone become very very laggy, not registering touch etc. Restarting the phone temporarily fixed lag and touch issues, but the problems came back quickly.
I also connected it to PC, but nothing happened.
Finally the battery has drained, and the phone has been plugged in for a few hours now, but still no charge. It's dead.
What could be the issue? Any suggestions? Seems like a hardware failure?
It's a 2 month old phone and I could be out $300+.
First time I bought a Xiaomi phone, this is a very scary and disappointing experience. I didn't drop the phone, no damage. As I said the phone was 100% fine before.
i just experiencing this issue exactly a week ago, at that point my battery were 7% down to 5% while trying "the fail" and when i plug the charge it says "plugged in, can't charge right now" but after 3 hours or so charging in while the phone was on, it bounce back to 7% and still displaying that message.
after trying to charge while the phone was off for more than 12 hours with no results, i gave up and place silica gel around the charging port for approx. 3 hours or so. and then i do this step.
i don't know what the pin point of the causing factor is and i don't know what step is unnecessary but this is what i do. i place silica gel around the port incase the port detecting moisture and preventing charge from happening, after 3 hour i try charging again using 18w quick charge brick while the phone is fastboot and turning it on. just like that the battery was charging.
after my battery were full i update the software to pie incase this is because of the software update (just like pixel 2 did), give this tutorial video a try*https://youtu.be/F9XNIbpC1yA some ppl able to do it in the first try, some 3x, some 6x, me? i finally achieve that on my 11x. just give it a shot and patience, no need root, ubl, etc etc
the fail. i tried using my friend charger (we have same phone) didn't work. tried using computer usb didn't work. tried using that quick charger brick without that silica gel part, didn't work. tried charging when the phone is off (i waited more than 12+hours) still didn't work.
based on that my conclusion were either there is moisture in the port and the sensor detect it and prevent the battery from charging up or the V9.6.17.0.ODIMIFE november update causing this problem.
again, this is what i do
-place/cover the charging port with silica gel
-wait approx. 3hour or more
-put the phone in fastboot mode
-charge the phone with 18w fast charger while in fastboot mode
-try to turn on the phone
the only post about this issue other than this was some guy in moto x4 thread on reddit, i don't know why there is so little info about this issue.

Seems like a hardware failure? idk, i'm still able to transfer data and listen to music through the dongle while this problem happening, so i assume it was software thing

Thanks for the response. I don't have silica gel but I placed the phone in rice for a few hours and then tried charging, it still won't work.
I can't get into fastboot either because the battery has drained completely by now.
Might have to take it to a mobile repair shop?

spoiler alert, that guy got his replacement phone while we (i assume you too) didn't even have access to official xiaomi service center ?
oh god, i just had it again, second time 10days later after the first one, on the latest pie update.
i'm legit scared ?, pray for my phones ?
but thanks god, the "plug in the charger while the phone on fastboot mode and turning it on"
still works, just like last time. even without the 18w fast charger.
I have the same problem. Battery drain could be the fingerpint sensor issue. The thing is the battery got really depleted and now, it seems the charger program/circuitry is consuming more power than it can charge. I tried several chargers, several usb-c cables, but nothing. Some hours ago the notification light blinked for some seconds and then it appeared as if it was indeed charging, it even showed the charging battery image ( the one without %, the one that appears when you have a really low battery charge ). But it has been hours trying and it doesn't do that anymore and there seems to be no way of making it charge and boot.
This is an appalling situation.
Similar problem, I purchase a Xiaomi Mi A2 by ebay, and passing 30 days (warranty expired) phone dead and never came to turn on, just flashing a white led, but nothing else, somebody has experimenting this problem and steps to revive the phone:crying:
same ****, guys.
I've tried several cables, couple of hard resets and etc. But now I have a pretty brick
I don't know if related but I had similar behavior after I dropped my a2 in the WC, after drying and figuring what prevented it to power on I discovered the USB plug at it's logic board internal connector as the parts preventing it to turn on, some cleaning an drying and my phone comeback.
Then today I observed it didn't charge, and the body warmed, It showed 50% charge, I rebooted and then it didn't turn on again, since I was doing some workout I figured the usb again got wet, I opened cleaned , dried assembly again and then it turned on w/o issue, but then the battery was showing 90% charge not 50% as before rebooting.
Maybe this your situation guys, it you think your phone somehow got wet, and you have no way to claim warranty (or too far from service center) try cleaning and drying the internal USB port connections. (Doit at your own risk).

My beloved Moto Z died in the same manner. I dropped it to the WC and finally died a few hours later. I'm happy now wirh my A2 but i miss the AMOLED screen [emoji24]

I tried to reset the phone in factory mode but no result, I tried with differents cables but no result. When the phone was plugged it was very very laggy but as soon as I unplugged it everything was coming back to normal.
Now I have run out of battery and my hopes to get my phone back to life are pretty low considering what I read on this topic. If anyone has a solution please tell us!
I would add that I always took care of my Xiaomi Mi A2 (no fall, no water spilled on it, no overheating) and everything was going well until a few hours ago. I didn't installed any new app since like a week ago (from the PlayStore) and I updated to 8.1 maybe a month ago. I thought waiting so long for Android Pie was annoying but this is way worse. If the situation doesn't evolve I will never buy a Xiaomi phone again. Very disappointed
Mi A2 stopped charging
After 2 month of use and Android pie update this stupid device refuses charging. I'm so very disappointed. I can't believe i fell to this Chinese trap. This is the last time I'm purchasing a Xiaomi phone! "Android One phone".... Yeah right!

In my case, after 4 months of use, just after Android pie update, I have stumbled on my MI A2 lite showing problems with USB connection and charging. The phone is not able to stablish a stable connection to the charger or the computer, it just keeps connecting and reconecting, begin charging and stopping charging.... If I leave the phone charging all night, it seems to finally fully charge. I can't figure how this problem may be related to Android Pie update, so I think it is just coincidence, and the usb connector is faulty, though I don't know the cause.... I think I will try to have it replaced
so did you fix the problem OP? i just started expiriencing what i think is the same problem.

if you go to the battery setting and it's says "plugged in, can't charge right now" then you should try plug in the charger while the phone on fastboot mode and turning it on
(read my previous comment) i experience this issue 2times and it's been running smoothly ever after

i just experiencing this issue exactly a week ago, at that point my battery were 7% down to 5% while trying "the fail" and when i plug the charge it says "plugged in, can't charge right now" but after 3 hours or so charging in while the phone was on, it bounce back to 7% and still displaying that message.
after trying to charge while the phone was off for more than 12 hours with no results, i gave up and place silica gel around the charging port for approx. 3 hours or so. and then i do this step.
i don't know what the pin point of the causing factor is and i don't know what step is unnecessary but this is what i do. i place silica gel around the port incase the port detecting moisture and preventing charge from happening, after 3 hour i try charging again using 18w quick charge brick while the phone is fastboot and turning it on. just like that the battery was charging.
after my battery were full i update the software to pie incase this is because of the software update (just like pixel 2 did), give this tutorial video a try*https://youtu.be/F9XNIbpC1yA some ppl able to do it in the first try, some 3x, some 6x, me? i finally achieve that on my 11x. just give it a shot and patience, no need root, ubl, etc etc
the fail. i tried using my friend charger (we have same phone) didn't work. tried using computer usb didn't work. tried using that quick charger brick without that silica gel part, didn't work. tried charging when the phone is off (i waited more than 12+hours) still didn't work.
based on that my conclusion were either there is moisture in the port and the sensor detect it and prevent the battery from charging up or the V9.6.17.0.ODIMIFE november update causing this problem.
again, this is what i do
-place/cover the charging port with silica gel
-wait approx. 3hour or more
-put the phone in fastboot mode
-charge the phone with 18w fast charger while in fastboot mode
-try to turn on the phone
the only post about this issue other than this was some guy in moto x4 thread on reddit, i don't know why there is so little info about this issue.
-----
Seems like a hardware failure? idk, i'm still able to transfer data and listen to music through the dongle while this problem happening, so i assume it was software thing
same...
please post an update so there's more information available regarding this problem and good luck

Hello,
I have something similar, I'm in Switzerland and running the Pie Rom from Nederland. I don't think it's link to Pie, maybe from a security patch because it didn't come at the same time for me, but this is what I got:
-When I plug my phone to a fast charger, I get "charging for a few second, then not charging"
-If I plug my fast charger and reboot the phone, the phone will charge (I need to double check but I guess slowly)
-I have a Audio-Adapter (USB-C, 3.5mm, USB Type C), so if plug the charger to this Adapter, and them plug the phone, the phone is charging fine (slowly).
So to me it looks like an issue with the fast charging...

No I was not able to fix it. I am talking with my credit card coverage and see what they can do.
I got a different phone in the meantime.
I also got rid of all my other Xiaomi products, never going to give this company a cent in the future. They are cheap for a reason !! Limited support and shady parts used in their devices. They can't be using quality internal components with such cheap prices.
Their mibox also randomly die.
Quantity over quality seems to be their mantra
Guys, it happened to me too,
I've flashed from android one Pie rom, to pixel experience.
Pixel Experience is great rom, was working brilliant for couple of days.
Then it stopped to charge. Now phone has discharged to 0% and I can't do anything.
My assumption is that getting new battery in exchange might help me fix the issue.
I've read that once you move to Pixel Experience Pie version form Android One 9.0 you need to flash kernel to. I did not do that.
Now waiting for the battery to arrive and will see what I can do with it.
